When Perovskite Solar Cells Are Cheap As Glass, What Then?

Researchers at The Fraunhofer Institute for Solar Energy Systems in Germany have come up with a business model that could upend the global solar marketplace. If it all works out, practically any facility that manufactures glass could churn out low cost perovskite solar cells for local markets. Aside from making solar panels cheaper, the local angle also reduces transportation costs and avoids sticky trade issues like the new US solar tariff.
